Title: Program execution device
Inventor: TSUBOI AKIRA
IPC: G06F9/45
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To improve the execution speed of a program described in an interpreter type language. SOLUTION: The program described in the interpreter type language is called in call units, compiled by a compiling means 2, and stored in a storage means 3. An executing means 4 reads corresponding call units out of the storage means 3 and executes them. A counting means 5 counts how many times the call units are executed by the executing means 4 and reports that to a decision means 6. The decision means 6 informs a reoptimizing means 7 that optimization in the call units need to be performed when the count result of the counting means 5 exceeds a specific threshold. A reoptimizing means 7 performs an optimizing process of high level for call units decided by the decision means 6 to be optimized again. After the optimizing process is completed, the executing means 4 regards the optimized call units as objects to be executed.
